heap-size

What information can I obtain from the performance.memory object in Chrome? What do these numbers mean? (are they in kb's or characters) What can I learn from these numbers? Example values of performance.memory MemoryInfo { jsHeapSizeLimit: 793000000, usedJSHeapSize: 10000000, totalJSHeapSize: 31200000 } What information can I obtain from the performance.memory object in Chrome? The property names should be pretty descriptive. What do these numbers mean? (are they in kb's or characters) The docs state: The values are quantized as to not expose private information to attackers. See the WebKit

I want to increase the heap size of my Glassfish. For that, I know that I can go up to 4GB: java -Xmx4000M -version java version "1.6.0_26" Java(TM) SE Runtime Environment (build 1.6.0_26-b03-384-10M3425) Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-384, mixed mode) I tried to set in domain.xml file the -Xmx to 2GB: <jvm-options>-Xmx2000m</jvm-options> But I am getting the following error: asadmin> start-domain Waiting for ... to start .Error starting domain ... The server exited prematurely with exit code 1. Before it died, it produced the following output: Error occurred during

is there some way to enlarge the heapsize of a c++ program? In android you can easily do that by declaring it as large in the manifestfile. I encountered this problem when I tried to allocate one billion array-elements on the heap. int main() { int size = 1000000000; int* nmbr = new int[size]; return 0; } C++ itself doesn't know what the "heap" is. This is an implementation issue, so you have to look into your compiler's documentation. Here's what a Google search for "MSVC heap size flag" found: http://msdn.microsoft.com/en-us/library/f90ybzkh.aspx Quoting from the MSDN page: The /HEAP option

When I'm using the graphical layout editor after 5-10 minutes of working I get the error "java heap size". I tried to increase size in eclipse.ini: -Xms512m -Xmx1024m But it doesn't helped. Please tell me who encountered this problem and how to solve it? Raghunandan Your eclipse.ini settings will take effect only if you change following: Run -> External Tools -> External Tool Configurations. go to configuration that u use, under jre tab -select option Run in same JRE in workspace. For more info on the topic have a look at this link. What are the best JVM settings for Eclipse? If sometimes you

I would like to know the relation between the mapreduce.map.memory.mb and mapred.map.child.java.opts parameters. Is mapreduce.map.memory.mb > mapred.map.child.java.opts ? Thanks, Kewal. mapreduce.map.memory.mb is the upper memory limit that Hadoop allows to be allocated to a mapper, in megabytes. The default is 512. If this limit is exceeded, Hadoop will kill the mapper with an error like this: Container[pid=container_1406552545451_0009_01_000002,containerID=container_234132_0001_01_000001] is running beyond physical memory limits. Current usage: 569.1 MB of 512 MB physical memory used; 970.1

Many posts have talked about Android heap size, and so far what I've found out is that the only common thing about max heap size is that it's at least 16MB, but that was the limit ever since API 3. For using more memory, people would suggest to use the NDK or anything that is beyond the "normal" Android development. Is there any Android version that has a requirement from the devices to have a larger heap size, so that I could start assuming a larger one and stop being so cheap on memory? Is there also a requirement about the flag of the large heap (from API 11 - honeycomb) inside the manifest
